What does execute_script() in Selenium does
execute_script method allows to execute JavaScript passed as string argument

execute_script()
execute_script() synchronously executes JavaScript in the current window/frame.
execute_script(script, *args)where: script: The JavaScript to execute *args: Any applicable arguments for your JavaScript. This method is defined as:
def execute_script(self, script, *args): """ Synchronously Executes JavaScript in the current window/frame. :Args: - script: The JavaScript to execute. - \\*args: Any applicable arguments for your JavaScript. :Usage: :: driver.execute_script('return document.title;') """ if isinstance(script, ScriptKey): try: script = self.pinned_scripts[script.id] except KeyError: raise JavascriptException("Pinned script could not be found") converted_args = list(args) command = None if self.w3c: command = Command.W3C_EXECUTE_SCRIPT else: command = Command.EXECUTE_SCRIPT return self.execute(command, { 'script': script, 'args': converted_args})['value']Examples
A couple of examples:
To open a new blank tab:
driver.execute_script("window.open('','_blank');")To open a new tab with an url:
driver.execute_script("window.open('https://www.google.com');")To retrieve the page title:
driver.execute_script('return document.title;')To scroll inti view an element:
